Architects of Death details how the gas chambers and crematoria that facilitated the murder and incineration of more than one million people in the Holocaust were designed not by the Nazi SS, but by a small respectable family firm of German engineers. Topf and Sons designed and built the crematoria at the concentration camps at Auschwitz-Birkenau, Buchenwald, Belzec, Dachau, Mauthausen, and Gusen. At its height, 66 Topf triple muffle ovens were in operation—46 of which were at Auschwitz.
These were not Nazi sadists, but men who were playboys and the sons of train conductors. They were driven not by ideology, but by love affairs, personal ambition, and bitter personal rivalries. Even while their firm created the ultimate human killing and disposal machines, their company sheltered Nazi enemies from the death camps. The intense conflagration of their very ordinary motives created work that surpassed in inhumanity even the demands of the SS.
But the company that achieved this spectacularly evil feat of engineering typify the banality of evil. In the 1930s their family firm produced apparatus for all sorts of industries—baking, brewing, the firing of ceramics. Ovens for crematoria accounted for only a small proportion of their business, but it is for these that the Topf brothers became infamous. Their name can still be seen stamped on the iron furnaces of Auschwitz.
